Dear Edward,
Using WIZ107SRv4_06p.bin file it worked. We thank you very much!
After uploaded this file we were able to detect the device via Configuration Tool as well and upload other versions of firmware.
We have tried to change the MAC address using the software WizMACTool(20151127).exe from this post (Problem with Wiz107SR: not found by configuration tool after firmware upgrade - #2 by irina_kim ), but the data file was messed up and the device was not detected in configuration tool anymore.
We used WizISP to reloaded the original data file. But, when detecting the device again with Configuration Toll, it seems to have a problem cause the datafile was messed up again.
So the question have changed. How to modified MAC Address correctly? Should WizMACTool be used or just modify directly from datafile?
We appreciate all the useful help.
Best Regards.
Felipe
